Porcine kidney xenotransplantation: From primate models to clinical reality

Animal Models and Experimental Medicine, EarlyView.
In the face of a critical shortage of human donor kidneys for end‐stage renal disease patients, porcine kidney xenotransplantation has emerged as a viable solution. This field has navigated major hurdles, including immune rejection, physiological incompatibilities, potential biomechanical differences and the risk of cross‐species infection. To overcome

Humanized immune system animal models and their recent applications

Animal Models and Experimental Medicine, EarlyView.
In this review, we provide an updated and comprehensive overview of the current state of humanized immune system animal model research. We discuss the variety of techniques used to produce humanized mice with their respective strengths and weaknesses, and evaluate the advantages and limitations of these models, including issues with incomplete immune ...

Angiotensin receptors: history and mysteries [PDF]

American Journal of Hypertension, 2000
Angiotensin receptors became relatively easy to study when radioactive derivatives of the peptide were synthesized for radioimmunoassays. Binding assays in vitro led to the discovery of receptors in many tissues different from those involved in the classic actions of angiotensin.

Chrysin alleviates pressure overload–induced myocardial remodeling through regulating the PI3K/AKT/NRF2 pathway–mediated oxidative stress response

Animal Models and Experimental Medicine, EarlyView.
In this study, we primarily simulated pathological myocardial remodeling induced by transverse aortic constriction surgery and found significant cardiac hypertrophy and fibrosis, characterized by deteriorated cardiac function. Oxidative stress response is considered as a pivotal pathological process, which contributes to inflammation and apoptosis of ...

The angiotensin II receptors type 1 and 2 modulate astrocytes and their crosstalk with microglia and neurons in an in vitro model of ischemic stroke

BMC Neuroscience
Background Astrocytes are the most abundant cell type of the central nervous system and are fundamentally involved in homeostasis, neuroprotection, and synaptic plasticity.

Idiopathic Intracranial Hypertension Is Characterized by a Distinct Proteomic Profile

Annals of Neurology, EarlyView.
Objectives The pathophysiology of idiopathic intracranial hypertension (IIH) is poorly understood and disease‐specific biomarkers are lacking. We aimed to shed light on IIH pathophysiology and identify disease‐specific biomarkers. Methods This prospective cross‐sectional cohort study included patients with new‐onset IIH and age‐, body mass index‐, and ...

Effect of angiotensin II and losartan on the phagocytic activity of peritoneal macrophages from Balb/C mice

Memorias do Instituto Oswaldo Cruz, 2004
Angiotensin II (AII), a product of rennin-angiotensin system, exerts an important role on the function of immune system cells. In this study, the effect of AII on the phagocytic activity of mouse peritoneal macrophages was assessed.

The 9+ month marathon: How pregnancy may have shaped human endurance capacities

The Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

Response of Renal Podocytes to Excessive Hydrostatic Pressure: a Pathophysiologic Cascade in a Malignant Hypertension Model

Kidney & Blood Pressure Research, 2017
Background/Aims: Renal injuries induced by increased intra-glomerular pressure coincide with podocyte detachment from the glomerular basement membrane (GBM).

Cytokine Pathways Driving Diverse Tissue Pathologies in Rheumatoid Arthritis

Arthritis &Rheumatology, EarlyView.
Rheumatoid arthritis (RA) is a complex systemic disorder characterized primarily by articular inflammation and destruction with associated functional loss and reduced quality of life. RA is also associated with extra‐articular disease, such as that of the lung, with potentially devastating clinical consequences. The critical importance of comorbidities,
